is the Lawsuit About and Why is it being Settled?

is a publicly traded Delaware corporation with principal executive offices located in Bothell, Washington. The Derivative Actions

were brought derivatively on behalf of Cocrystal and allege that the Individual Defendants breached their fiduciary duties by

allegedly making and/or causing Cocrystal or its predecessor, BioZone Pharmaceuticals, Inc. ("BioZone") to make misrepresentations

and/or omissions of material fact in public statements, failing to maintain internal controls at Cocrystal or BioZone, engaging

in allegedly improper promotion or manipulation of the market for BioZone's securities, or aiding and abetting such breaches

deny that a pre-suit demand on Cocrystal's board of directors would have been futile and, therefore, excused. The Individual

Defendants have denied, and continue to deny, any wrongdoing or liability arising out of or relating in any way to the events,

conduct, statements, acts, or omissions alleged in the Derivative Actions. The Individual Defendants deny that Cocrystal or its

shareholders were harmed by the conduct alleged in the Derivative Actions, and further assert that, at all times, they acted in

good faith, and , to the extent they were officers or directors,in a manner they reasonably believed to be and that was in the

best interests of Cocrystal and Cocrystal's stockholders. The Individual Defendants assert that they have meritorious defenses

to the claims in the Derivative Actions. Nonetheless, Defendants have entered into the Stipulation, without admitting or conceding

any fault, liability, wrongdoing, or damage whatsoever, in order to avoid the burden and expense of further litigation.

Court has not decided in favor of the Individual Defendants or Plaintiffs. Instead, both sides agreed to the Settlement to avoid

the distraction, costs, and risks of further litigation. Plaintiffs and the Company believe that the corporate governance enhancements

that the Company will adopt as part of the Settlement provide a substantial benefit to Cocrystal and its stockholders, and Plaintiffs

and Plaintiffs' Counsel believe the Settlement is in the best interests of Cocrystal and its stockholders.
